To all whom it may concern.'

Be it known that I, JOHN D. J onus, a citizen ofthe United States, residing at Walla Walla, in the county of Walla Wallaand State of Washington, have invented certain useful Improvements in Piston Rods, of which the following is a specification, reference being had therein tothe accompanying drawing.

This invention relates to improvements in piston rods, and more particularly to rods used in explosion engines, one object of the invention being2 the provision of an arrangement `by means of which the connecting end for attaching tothe crank shaft may be eiliciently lubricated to reduce the friction and \consequent wear uponthe bushing of such connection. A further `object of this invention is th provision .of` an automatically n lubricated crankshaft connection for piston rods by means ofwhich an incased lubricant containing chamber is provided to encircle the bushing and supply lubricant therethrough to the 4crank shaft and to the bushing, the lubricant being supplied to said chamber during the movement of the crank shaft and piston rod in such a manner as to insure the proper dispensing ofthe lubricant which also tends to keep the frictional parts cooled.

With the foregoing and` other objects in view and which will appear as the description of the invention proceeds, said invention consists of a novel combination and arrangement of parts hereinafter described and ,partcularl pointed out 'inthe claims, it

emg possihle to lchange the detail construction which is only limited'by the scope of what is claimed.

` In Athe..,accompanying drawings:

Figure 1` is a longitudinal sectional view through the lower end of a piston rod conv structed to and embodyingthe venton. V

Fig. 2'is asection taken at right angles to that` shown in Fig. 1 and slightly to one side ofthece'n'ter web.. v

Fig; Bfis .ijlplan view of the lower section Apresent inof the connecting portion fandgthe lower -Fi @is a. view similar 'to FigSl of a mod eil-form.

F ig. 45de a view-similar to Fig. 2.0i the y constructionshown in Fi 4.

Fig.Y 6 isa plan view' o the lower section of the bushing and connecting member of' that shown in Figs. 4 and 5.

lReferring to the drawings, and-more particularly toFigs. 1, 2, and 3, the corresponding parts inFigs. l1, 5, and 6, being primed, the numeral l designates the central Web of the rod proper4 which has the usual fianges 11 which in this instance at the lower ends are connected together by means of the inclined wall 12 to provide the two lubricant receiving and delivering receptacles 13, one upon each side of the web and each one of which is provided with its dispensing opening or aperture 14.

Formed integral with the web and flanges and the walls 12 is the upper section 1-15. of the connecting end of the rod which also provided with the central segmental lug 16 which projects inwardly and provides with the section and the upper section 17 of the bushing which is held in place by the screws 18, the lubricant receiving channel 19.

At opposite sides of the connecting section 15 is an apertured web 20 which alines with the apertured web21 of the'lower connectfing section 23 which is provided with the lubricant'receiving chamber 22 sealed upon the two conveying portions 28 and 29 hav- .ing the .openings into both of the receptacles 13.y l Y It will thus be seen thatas the present rod moves in the crank Ak'zase in its usual circle that with'the constructign shown in Figs. 1 and 2, the spout 27 will-,dip into the lubricant within the crank 'cas'i'n by such action will be glirected through the channels 28' andi 29 and through the openings 30 into thereceptac1es 13 rom whence it will be dispensed through the openin 14 intil the annular chamber .19--22 to e finallydirected throughthe apertured por- 'tions of the bushing '17--22 to 'the sur-` rounding portion ofw the crank shaftknotaiuo shown. I, V

v which consists ofthe mletf. portion 27 and and such lubricant Also in this'construction any of the lubricant splashing inwardly upon the web of the rod and between the flanges 11 will fall b'y gravity into the receptacles 13 and pass in a similar manner into the annular chamber 19-22.

In the construction shown in Figs. 4 and 5, the annular chamber is the only one r0- vided, this being illustrated to show cw the scoop lubricating device may be chspensed with. From the foregoing description it is evi- Vdent that with a self-lubricating connection as herein set forth, that the bushing will be properly lubricated and by such bricant surrounding the same be sufficiently cooled to consequently reduce the friction and wearing of the bushing.

Where found desirable only one receptacle 13 may beemployed in which event the diaphragm lug 16 will be dispensed with, this ug acting as a directinfr means to insure the proper distribution of the lubricant for passage into the section 19 of the annu-lar Chamber.

What I claim as new is:

1. A piston rod having a crank shaft con.- necting end arovided with a lubricant reccivin'g cham er, and a bushing in the connectin end and forming the inner wall of said c amber.

2l A piston rod having a crank shaft con- .i necting end provided with a lubricant receiving chamber, and a bushing in the connectin said c amber, and means for directing the lubricant to said chamber, said bushing being provided with lubricant outlets.

3. A piston rod having a sectional connecting end provided with an annular cham# ber, said chamber being provided with lubricant receiving openin adjacent the juncf tion of the rod with t e connecting end.

4. A piston rod having a"sectiona1 coni-fnecting end provided with an annular chamber, said chamber being provided with lubricant receivin openings adjacent the junction of the r with the connecting end, and a bushing fitting in the connected end and forming the inner wall for the chamber,

said bushing being provided with lubricant outlets.

5. A piston rod having a sectional connecting end provided with an annular chamber, said chamber being provided with'lubricant receiving openings adjacent the junction' of thezyrod with the connecting end, and an auxiliary lubricant' directing memend and forming the inner wall of ber in communication with the inlet opening of the chamber and having its inlet dispose to scoop the lubricant during the movement of the rod.

6. A piston rod having a rece tacle at the lower end of the rod; a sectiona connecting end carriedby the rod and provided with an annular lubricant receivin chamber, said chamber being in communication with the rst receptacle, and af bushing havin outlet ports forming the inner walls of t e annular lubricant chamber.

7. A piston rod, having a receptacle at the lower end of the rod, a sectional connecting end carried by the rod and provided with an annular lubricant receiving chamber, said chamber bein in communication with thc first receptac e, a bushing having* outlet ports forming the inner walls of the annular lubricant chamber, and an auxiliary scoop carried by the connecting cnd and having an inlet at the opposite side to the outlet, which outlet is in communication with said receptacle.

8. A piston rod having a central longitudinal web, two receptacles one upon each side adjacent one end of the web, a sectional connecting end one section of which is formed intecrral with the web and the rcceptacles and is provided with an aperture in communication with said receptacles, the two sections of the connecting end being provided with an annular lubricant chamber, the inlet of which is said openings, and a sectional bushing mounted in the sections of the connecting ends and forming the inner walls of thechamber.

9. A piston rod havin a. central longitudinall web, two receptac es one upon each side adjacent one end of the web, a sectional connecting end, one section of which is formed integral withlthe Yweb and the receptacles and is provided with-an aperture in communication withj'aid rece tac es, the two sections of the connecting en being rovided with an annularl lubricant cham er,
